Taoiseach Enda Kenny said today that he cannot give Junior Minister Lucinda Creighton what she wants in the abortion legislation as that would make it unconstitutional.
The European Affairs Minister looks set to be the most high-profile rebel when the final votes on the legislation takes place on Wednesday.
She said that she cannot support the laws if the suicidal intent provision remains within it.
Speaking in Waterford this afternoon, Enda Kenny says he cannot change that provision.
"The question of suicide intent is an issue that was dealt with by the Supreme Court decision," he said.
"We as a Government, and I as the Taoiseach, I'm not able to 'unpick' that Supreme Court decision.
"And therefor, to attempt to do so, would first of all render any Bill unconstitutional, and secondly would lower the more subjective issue, that is suicide, as was determined by the European Court."
